I've added a picture.(adsbygoogle = window.adsbygoogle || []).push({});

The system shown to the right is in equilibrium with the center string exactly horizontal.

Mass # 1 = 42 kg.

Mass # 2 = 50 kg.

È = 31 degrees.

===========

A) Tension in left most string?

B) Tension in center string?

C) Tension in right string?

D) What is the angle Ö on the right string?

=======

a) Not too bad at all. Just did sin 31=(m1*g)/T1

T1=799.16N

b) Now I'm stuck. It probably is really easy, but I'm missing something. I drew the FBD, and so I got a force from m1 and m2 downwards, a T1 force to the left, and a T3 force to the right. But its not helping much, at least to me. Yes, its a static equilibrium equation, so sum of all forces in x and y and torques equal zero, but I don't know where to start correctly.
